Abstract: A method of edge bevel rinse. First, a wafer having a coating material layer disposed thereon is provided. A light beam is optically projected on the wafer to form a reference pattern. The reference pattern defines a central region, and a bevel region surrounding the central region on the surface of the wafer. Subsequently, the coating material layer positioned in the bevel region is removed according to the reference pattern.
